v Inventor William H. Goefisch Attorney Patented Jam: 3, 1933 UNITED STATES PATENT o FFICE" BROODER ALARM Application filed April 4,

The present invention relates to an alarm for brooders and has for its prime object to provide a thermostatic controlled circuit closer whereby an alarm may be energized when the temperature becomes too low or too m high in the brooder.

Another very important object of'the invention resides in the provision of an improvement of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable, thoroughly elficient and reliable in its use and operation and otherwise well adapted to the purpose for which it is designed.

a With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings: 1 g V Figure l is a side elevation of a brooder showing a portion of the hood broken away so as to illustrate the position of my improved structure,

Figure 2 is a top plan view thereof,

Figure 3 is a top plan view of the box with the cover removed,

Figure 4 is a longitudinal vertical section therethrough Figure 5 is a vertical transverse section therethrough. I 1

Figure 6 is an enlarged detail horizontal section showing the manner in which one end of the board is mounted in one end wall of the box,

with the curved bracket thereon, and

Figure 8 is a perspective view of the thermostat wafer and the switch arm attached thereto. 1

Referring to the drawings in detail it will be seen that the numeral 5 denotes the hood of a brooder with a heating element such as a lamp 6 mounted therein.

A box B is mounted on the lamp as illustrated in Figures 1 and 2 and comprises a bottom 7 end walls 8 and side walls 9 and 10. The end walls 8 are provided in their central upper portions with transversely extending elon- Figure 7 is a perspective view of the board 1929. Serial No. 352,439.

gated interior depressionsll for receiving the ends of a board 12 which may be sprung in place" and thus supported in ahorizontal 'position in the upper portion of the box. Oblong opening 14 is provided in the wall 9 opposite, 5 the board 12 and has a screen 15 therein, A cover 16 is provided for the box and is preferably'liingedly mounted or engaged as at 17 with the wall 9 and has a locking means 18 associatedwith thewall 10. V The wall 9 is disposed adjacent the lamp so that the heat of the lamp may readily pass through the opening 14. g

A thermostat wafer 20 is anchored meat 21 a on the board 12 and has a "rod 22 extending 65 therefrom in substantial parallelism with the board 12 an'dthereov'er. A curved bracket member 24 has one end fixed to the board by means ofcontact bolts 25 so as to rise from theboard and the upper end thereof has a 7 screw 27 adjustably mounted therein. 7

The'terminal of the arm 22 is disposed between the contact screws'27 and the contact bolts 25. Thebattery 28 is located in the bottom of the box B and wire 29 from one ter- 7 minal is connected as at 30 with the intermediate portion of the arm 22.

A wire 30 leads fromthe other terminal of the battery to an alarm'such as an electric bell 31 and a wire 32 leads from the electric bell to r the bolt 25. V

' From the above detailed description it will be seen that when the temperature rises to a certain degree in the 'brooder the wafer 20 will be expanded so as to cause the arm 22 to engage contact screws 24 thereby closing the alarm circuit. On the other hand should the temperature fall in the brooder too low then the wafer will contact and allow the arm 22 to engage the contact bolt 25 thereby closing the alarm circuit.

Obviously the temperature at Which the alarm may be sounded either in raising or lowering the arm 22 may be controlled by adjusting the bolt 25 and the screw 27 I It is thought that the construction, operation, utility and advantages ofthis invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention, however, has been disclosed in considerable detail, merely for the purposes of exemplification since in actual practice it attains the fea- 5 tures of advantage enumerated as desirable in the statement of the invention and the above description. e

It will be apparent that changes in the details of construction, and in the combina- 10 tion and arrangement of parts may be resorted to without departing from the spirit @or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

' Having thus described my invention, what 15 I claim as new is:

In an alarm of the class described, a closed V "casing having depressions in itsopposite end walls provided with resilient sides, said oa s: ing ha a h at a p n g on 0t its sidewalls, a thermostaticswitch mount- 1 ed in andvcompletely housed by said casing 'includ'ng' a supporting member having snap engagement with said depressions, a. thermo-v re pon i w er secu ed to s supp 2 5 member and arranged adjacent said heat admitting opening, an arm fixed at one end to a said wafer, a curved substantially U-shaped bracket, a contact bolt adjustable thru said upport ng memb r and the lower n f s a; bracket and securing said bracket to said supporting member, a contact bolt adjustable thru the upper end of said bracket, said- C0111 tact bolts being arranged in the path of move-v ment ofthe f ree end of said arm, and an elec-.

9 trical alarm circuit including said arm and contact bolts, e p

In testimony whereof I aflix my signature.
